# Introduction

Use independent records whenever you want to write your own data records the blockchain, but do not want them to be linked together.

Independent records (just called records in this document) have no explicit relationship to any other records on the blockchain. You can, of course, maintain record linkage information within your own applications and data.

Independent records provide the following capabilities:

* Approximate event timestamps (+/- 10 minutes)
* Independence
* Persistence
* Data security
* Evidence and verification of operations

An independent record is written to the blockchain inside a transaction.
